2 Configure the following settings:
○ Enable SIP Enable
○ Transport Protocol This field determines the protocol the system uses for SIP signaling. The
SIP network infrastructure in which your Polycom HDX system is operating determines which
protocol is required. You can choose from the following options:
» Auto enables an automatic negotiation of protocols in the following order: TLS, TCP, UDP.
This is the recommended setting for most environments.
» TCP provides reliable transport via TCP for SIP signaling.
○ User Name Enter the directory number of the OpenScape Voice. This field specifies the SIP
address or SIP name of the system — for example,
[e-mail]. If you leave this field blank, the system’s IP
address is used for authentication. In a Siemens environment, this setting is the Subscriber
number provided by the OpenScape Voice administrator.
○ Domain User Name Digest Authentication User Name. This field specifies the name to use for
authentication when registering with a SIP Registrar Server — for example,
[e-mail]. If the SIP proxy requires authentication, this field and the password
cannot be blank.
○ Password Digest Authentication Password. This field specifies the password that
authenticates the system to the Registrar Server.
○ SIP Registrar Server OpenScape Voice IP or DNS-Name (preferred). This field specifies the IP
address or DNS name of the SIP Registrar Server. By default for TCP, the SIP signaling is sent to
port 5060 on the registrar server. By default for TLS, the SIP signaling is sent to port 5061 on
the registrar server.
Enter the IP address and port using the following format:
<IP_Address>:<Port>
<IP_Address> can be an IPv4 address or a DNS hostname such as
servername.company.com:6050. Hostnames can resolve to IPv4 or IPv6 addresses.
Syntax Examples:
To use the default port for the protocol you have selected:
10.11.12.13
To specify a different TCP or UDP port:
10.11.12.13:5071
Enter an IPv6 address using the following format:
[<IPv6_Address>]:<Port>
An example of an IPv6 address is:
[2001:db8:85a3::8a2e:370:7334]:8032:8033
